Vacuum ultraviolet fluorescence is observed from high density helium (up to three times liquid density) in microbubbles in implanted aluminum and tin. The fluorescence is excited by bombardment with low-energy electrons (<5 keV). The resulting spectra are attributed to a combination of excimer (higher wavelength) and atomic (lower wavelength) fluorescences. The efficiency of the process is such that it has recently been proposed for the construction of a new solid state vacuum ultraviolet photon source.
